Objective: Single fiber EMG (SFEMG) is a potent electrophysiological method to evaluate impaired neuromuscular transmission, and allows sensitive diagnosis of neuromuscular transmission abnormalities such as myasthenia gravis. The jitter and fiber density values are different for various muscles and age groups and the reference values increase with age. In this study, we evaluated the reference values of jitter and fiber density of frontalis muscle in healthy subjects older than 70 years.
